Finally got some pics up for anyone interested. Here

 

 

Both pistons and rods are custom made to spec. Pistons are 98mm (5mm overbore) for 5.0l capacity CR will be ~12:1

nice!

 

probably a silly question, but is there a reason fot the pistons being flat, and the zed pistons having shaped crowns?

Depends on the size of the combustion chamber and the compression ratio you want. Beacuse I've overbored the chamber is now relatively smaller than is was so hence flat tops and no bulges to increase CR. Generally flat tops give better combustion as there are no lumps and bumps to impede the flame front as it spreads across the chamber.

It's pretty common to see dished pistons on turbo engines used to lower the CR, unless you go crude and use a thicker gasket.

Very nice H beam custom conrods :bow:

Quality

looks quality

 

CR 12:1 :duffer:

 

what sort of torque figures are they getting in the states with similar setups john?

And to jump in, PACE also did a great job with the custom pulleys (bottom photo shows the old one for comparison):

 

BEAUTY :bow:

Ohhhhhhhhhh hurry the fudge up and get this finished John :D I cant wait to here it :)

 

Some car part porn pics there bud! :bow:

 

Catch up with you soon

Greg, not entirely sure as no one to my knowledge has done this before. There are some stroked 5.0l (lower rev limit) and a few alky burning ones pushing ~900bhp@10,000rpm in boats.

Rich, Oddly enough I'm just as keen as you to see it finished!
